Behold, the day of the LORD cometh, and thy spoil shall be divided in the midst of thee.
Behold, the day of the Lord cometh - in which He shall vindicate His justice, by punishing the wicked, and then Behold, the day of the Lord cometh - in which He shall vindicate His justice, by punishing the wicked, and then saving His elect people (Joel 2:31; Joel 3:14; Malachi 4:1; Malachi 4:5).
And thy spoil shall be divided in the midst of thee - by the foe; secure of victory, they shall not divide the spoil taken from thee in their camp outside, but "in the midst" of the city itself.
